Speed, Scale, Reliability and the Pursuit of Programmability

Speed, Scale, Reliability and the Pursuit of Programmability

As networking moves from monolithic to disaggregated infrastructure, the necessity of programmability has become existential, be it physical or software-defined networks (SDN). A common thread runs through these movements: the need for control.

As the notion of control continues to evolve, it will drive significant changes to the systems that form the foundations of the network.

Black Hat 2018: Securing the Expanding Cyberattack Landscape

Black Hat 2018: Securing the Expanding Cyberattack Landscape

There is a recurring theme at Black Hat every year: security researchers come together and show the world how to hack into systems and things. This year was no exception.

The sheer size of the cyber-attack surface becomes more daunting by the day. Networks now connect data centers and on-premise hardware to private and public clouds and IoT devices operating at the network edge, exposing more potential entry points and increasing vulnerability.

Resources Outline the New Essentials for Data Center Design

Earlier this year, Forrester conducted research into the data center networking market. In the report titled The Forrester Wave™: Hardware Platforms for Software-Defined Networking, Q1 2018, lead research analyst Andre Kindness looked at a number of criteria split across current offerings, strategy, and market presence.

Is SD-WAN the new MPLS?

Is SD-WAN the new MPLS?

As SD-WAN adoption matures and moves from “peak of inflated expectation” to “slope of enlightenment”, a question that I hear and many technologist ponder over is whether SD-WAN is the new MPLS. If you asked this question to a distinguished engineer they would violently disagree at a technical level comparing the difference from an OSI layer and packet/protocol formats perspective.

Windows Exploitation and AntiExploitation Evolution

Windows Exploitation and AntiExploitation Evolution

Windows has been a target of hackers for a long time. The reason is simple: it is the OS with the largest deployment footprint around the world. Hackers discover vulnerabilities in Windows OS software as well as the various software that support Windows OS. Exploits as well as exploit mitigation techniques have evolved over the years.

VPNFilter: a global threat beyond routers

VPNFilter: a global threat beyond routers

When first publicly announced on May 23, the threat dubbed VPNFilter was thought to only infect some brands of home routers and Network Attached Storage devices. While it was known that the list of router brands was probably not complete, little did we know that the malware has the ability to infect the very computers sitting behind those routers and firewalls.
